BOTANICAL CLASSIFICATION/CULTIVAR DESIGNATION

[0001] Nemesia hybrid cultivar Innkablue

BACKGROUND OF THE INVENTION

[0002] The present invention relates to a new and distinct cultivar of Nemesia plant, botanically known as Nemesia hybrid and referred to by the name ‘Innkablue’.

[0003] The new Nemesia is a product of a planned breeding program conducted by the Inventors in Gensingen, Germany. The objective of the program is to create new compact Nemesia cultivars with numerous flowers, unique flower colors and fragrance.

[0004] The new Nemesia originated from a cross by the Inventors of a proprietary Nemesia hybrid selection identified as code N98Sä3tetra2, not patented, as the female, or seed, parent with the Nemesia hybrid cultivar Hubbird, disclosed in U.S. Plant Pat. No. 12,014, as the male, or pollen, parent during the summer of 1999. The cultivar Innkablue was discovered and selected by the Inventors as a flowering plant within the progeny of the stated cross in a controlled environment in Gensingen, Germany during the summer of 1999.

[0005] Asexual reproduction of the new Nemesia by terminal cuttings taken in a controlled environment in Gensingen, Germany since 1999, has shown that the unique features of this new Nemesia are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

[0006] The new Nemesia has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.

[0007] The following characteristics have been repeatedly observed and are determined to be basic characteristics of ‘Innkablue’ and distinguish ‘Innkablue’ as a new and distinct cultivar:

[0008] 1. Upright, outwardly spreading to trailing plant habit.

[0009] 2. Vigorous growth habit.

[0010] 3. Freely branching habit.

[0011] 4. Numerous dark violet-colored flowers.

[0012] Plants of the new Nemesia differ primarily from plants of the female parent selection in the following characteristics:

[0013] 1. Plants of the new Nemesia flower earlier than plants of the female parent selection.

[0014] 2. Plants of the new Nemesia have larger flowers than plants of the female parent selection.

[0015] 3. Plants of the new Nemesia are more freely flowering than plants of the female parent selection.

[0016] Plants of the new Nemesia are most similar to plants of the male parent, the cultivar Hubbird. Plants of the new Nemesia differ from plants of the cultivar Hubbird in the following characteristics:

[0017] 1. Plants of the new Nemesia are more vigorous than plants of the cultivar Hubbird.

[0018] 2. Plants of the new Nemesia have larger flowers than plants of the cultivar Hubbird.

[0019] 3. Flowers of plants of the new Nemesia are more fragrant than flowers of plants of the cultivar Hubbird.

[0020] 4. Flowers of plants of the new Nemesia are more intense dark violet in color than flowers of plants of the cultivar Hubbird.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

[0021] The accompanying colored photographs illustrate the overall appearance of the new Nemesia, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Nemesia. The photograph at the bottom of the sheet comprises a side perspective view of a typical potted plant of ‘Innkablue’ that was about ten weeks old. The photograph at the top of the sheet comprises a close-up view of typical flowers of ‘Innkablue’.

DETAILED BOTANICAL DESCRIPTION

[0022] The aforementioned photographs and following observations and averaged measurements describe plants grown in Bonsall, Calif., in an outdoor nursery during the spring with day temperatures ranging from 18 to 35° C. and night temperatures ranging from 7 to 18° C. After rooting, plants were grown for about ten weeks in 15-cm containers with one plant per container. Color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
